I used to do all the good citizen things, including forwarding the child porn ads to the Aussie authorities, the scams to the anti scam sites, etc, but after the police told me in an email that they wanted me to stop sending the stuff!!!!, and the 'investigation team' taking so long to get around to looking at the sites that I got emails telling me the sites were not working!!! I just delete it all now, mailwasher recognises the russian sites and just ignores them.
With over 100 Spam a day anyway, the amount of time and resources thus 'wasted' was not worth it to me, so I gave up.
